The present invention relates to the use of compounds with a potentiating effect on the activity of antibiotics that are activatable via the EthA enzymatic pathway, for the preparation of a medicament for preventing and/or treating mycobacterial infections such as tuberculosis and leprosy, to pharmaceutical compositions comprising them in combination with an antibiotic that is activatable via the EthA pathway, to compounds having a potentiating effect on the activity of antibiotics that are activatable via the EthA enzymatic pathway, to pharmaceutical compositions comprising them and to their use as medicaments, especially medicaments for preventing and/or treating mycobacterial infections such as tuberculosis and leprosy.
hetero-Michael reactions among various oxygen, sulfur, and nitrogen nucleophiles and α,β-unsaturated compounds were carried out in the presence of catalytic amounts of o-benzenedisulfonimide as Brønstedacid organocatalyst. The reaction conditions were very mild, and the yields of target products were good. The catalyst was easily recovered and purified, ready to be used in further reactions. This ability
A new and convenient method for the acid-catalysed Michael addition reactions of alcohols, thiols and amines to methyl vinyl ketone has been developed using the ionic liquid ethyltri-n-butylphosphonium tosylate. The reaction conditions are mild and obviate the need for toxic and expensive Lewis acid catalysts, offering advantages over more commonly used systems.

The first examples of the Favorskii-typerearrangement of α-monochloro ketimines are reported. The regiospecific opening of the intermediate cyclopropylideneamines parallels the opening of cyclopropanones under Favorskii-conditions.
